And so Nohbo, meaning No Hair Bottles, was created.

According to the Nohbo site, the shampoo drops are vegan and cruelty-free, as well as paraben- and sulfate-free. They're designed to be like detergent pods, wrapped only in a thin biodegradable film rather than coming in an entire plastic bottle.

The box the pods come in is also made from biodegradable plant material, according to the site.

Stern is serious about helping the environment with these pods.

The Nohbo site says that after appearing on "Shark Tank" in 2016 and securing funding from Mark Cuban, Stern and his team has worked tirelessly to bring his product to market.

Simply hold a pod under water for four seconds then use the shampoo like normal. A single drop holds 5 milliliters of shampoo and is good for one wash.

According to the site, in spring 2019, Nohbo is expanding their product line to include conditioner, body wash and shaving cream. Insider reported that Stern also wants to partner with hotels to decrease the amount of little plastic bottles that they currently use.

That way he'll really be able to disrupt the bathroom plastics industry.

But for now, the rosemary, mint and sandalwood shampoo drops are a pretty good deal — for your hair and the environment.
